Venseri MS660 Carburetor for MS640 MS650 MS 660 064 066 Chainsaw 0000 120 1653 with Ignition Coil Air Filter Turn Up Kit

This is a great kit! I was having problems with fuel delivery on my 660 and this definitely got it back running. It includes the whole fuel system from tank to cylinder including the rubber intake manifold, carb, the impulse tube (fuel pump), the fuel filter and uptake in tank tube and the air filter even included the foam insert within the paper element as well.Also includes the whole ignition as well. The grounding wire for shutoff was a little short so I used the original from the saw.To install the coil just stick a business card between the coil and the flywheel then rotate the flywheel around to line up the magnets with the coil, clamp it down securely, and pull the card out - that should give you about 0.010" for the gap which is right in the suitable range (0.006" - 0.012"). Just don't use some super thick laminated card and you should be OK.After setting the two screes to 1 full turn out it started right up after 3 or 4 pulls (had to pull up fuel since the whole system way dry to begin with). Now it'll fire up within 2. Still need to dial it in a little - seems a little rich on full throttle with the 1 turn on the screws.There were a couple I didn't bother with that I think are for the oil system (coarse filter uptake and a roller bearing). Parts all seem of good, solid quality - better than the previous Chinese knockoff carb I had on it before.Very happy with the kit and highly recommend it. As long as you have some decent compression this kit should fix it. If you don't, just add a big bore kit and you basically have nearly an all new saw.

Calibrator fit and saw runs again. Time will tell if it lasts. But for the time being im running hot and sharp

Bought this for my Stihl chainsaw. Would not ever buy again. It fired up 3 times fine. Fourth time it would not start and flooded my saw out so bad gas ran out of the muffler with one pull.

I liked the price.
